Yakaderera ruzha amplifier (LNA), frequency 9K ~ 1GHz, kuwana 30dB, ruzha nhamba (NF) 2dB

Yakaderera ruzha amplifier chinhu chakakosha muRF / microwave masisitimu, anonyanya kushandiswa kukwidziridza asina kusimba masaini uku uchideredza imwe ruzha. Mabasa ayo makuru uye mamiriro ekushandisa ndeaya anotevera:

Core Functions:

1. Kukwidziridzwa kwechiratidzo
Wedzera iyo amplitude yemasaini asina kusimba anogamuchirwa nema antennas kana masensa kuti ave nechokwadi chekugadzirisa neanotevera maseketi akadai semisanganiswa uye ADCs.
2. Kudzvinyirira ruzha
Nekugadzirisa dhizaini uye nekushandisa yakaderera-ruzha zvinhu, iyo yega yakaunzwa ruzha nhamba (NF) inodzorwa mukati meiyo 0.5-3dB (yakanaka amplifier NF = 0dB).

Mamiriro ekushandisa:

1. Radar system
Muchiuto radar (senge airborne fire control radar) uye civilian radar (yakadai semotokari millimeter wave radar), LNA inoshandiswa kukwidziridza iyo isina simba echo chiratidzo (signal-to-noise ratio SNR <0dB) inoratidzwa nechinangwa. Kana ichipfuura nepakati pekusimudza link neNF <2dB, radar inogona kuziva zvinangwa zvine kure kana kudzika RCS (radar cross chikamu).
2. Wireless communication system
Low noise amplifier ndiyo yakakosha chikamu che5G/6G base zviteshi, setiraiti kutaurirana, uye nharembozha inogamuchira zvinongedzo. Iyo ine basa rekudzika-ruzha amplification (NF <1.5dB) yeasina simba RF masiginecha (akadzika se -120dBm) akabatwa neantenna pamberi pechiratidzo chekuderedzwa, zvakanyanya kuvandudza sisitimu inogamuchira kunzwa. Semuenzaniso, mumillimeter wave frequency band (24 - 100GHz), LNA inogona kubhadhara kusvika ku20dB yekurasika kwegwara, kuve nechokwadi kugadzikana kwekumhanya-mhanya kwedata.
3. High precision yekuongorora chiridzwa
Mumidziyo yakadai sema spectrum analyzers uye vector network analyzers (VNA), LNA inotarisisa zvakanangana nekuita ruzha rwechiridzwa uye simba renji. LNA inogona kuvandudza kunzwisiswa kwechiridzwa nekusimudzira iyo nV chiyero chakayerwa chiratidzo kune inoshanda quantization renji yeADC (senge 1Vpp). Zvichakadaro, ultra-low noise coefficient (NF <3dB) inogona kunyatso kudzikisa kuyerwa kusavimbika uye kuderedza kuyerwa kukanganisa.
4. Wedzera nzvimbo dzekushandisa
Radio astronomy: The FAST telescope inovimba nemvura helium yakatonhodzwa LNA (NF ≈ 0.1dB) kutora 21cm mitsara inoonekera muchadenga.
Quantum komputa: Kusimudzira μV nhanho masiginecha (4 - 8GHz) ye superconducting qubits inoda pedyo ne quantum muganho ruzha kuita.
Kufungidzira kwekurapa: Midziyo yeMRI inosimudzira μV nhanho yenyukireya magineti resonance masaini kuburikidza neasiri magineti LNA, ine chiratidzo-ku-ruzha reshiyo inodarika 10dB.

Qualwave Inc. inopa masikisi-ruzha amplifiers kubva pa9kHz kusvika 260GHz, ine ruzha rwakadzika se0.8dB.
Iyo QLA-9K-1000-30-20 modhi, iyo yakanyatsogadzirirwa kutsvagisa kwesainzi uye mashandisirwo ekutaurirana, inowana yakanakisa kuita chiyero che30dB kuwana uye 2dB ruzha nhamba mu9kHz ~ 1GHz frequency bhendi.
